drm/i915: Keep rings pinned while the context is active
Remember to keep the rings pinned as well as the context image until the
GPU is no longer active.
v2: Introduce a ring->pin_count primarily to hide the
mock_ring that doesn't fit into the normal GGTT vma picture.
v3: Order is important in teardown, ringbuffer submission needs to drop
the pin count on the engine->kernel_context before it can gleefully free
its ring.

Fixes: ce476c80b8bf ("drm/i915: Keep contexts pinned until after the next
kernel context switch")
